<div id="howWrap">
<div class="how-grid">
<div class="how-card"><h4>1 Β· Structure β numbers</h4><p>Every molecule becomes a <b>2,048-bit Morgan fingerprint</b> (which substructures it contains) plus a block of <b>physicochemical descriptors</b> (logP, MW, TPSA, H-bondingβ¦). That one shared vector feeds every model β the same structure-to-property representation QSAR has leaned on for decades.</p></div>
<div class="how-card"><h4>2 Β· Taste β 6 trained heads + 2 rules</h4><p>Six <b>random-forest</b> classifiers (sweet, bitter, umamiβ¦) each return a probability, scored by an honest held-out <b>CV-AUROC</b>. Sour and salty are solution / ionic effects, not molecule-shape ones, so they're transparent <b>rules</b> β not faked models. A sweetness-intensity regressor estimates relative-to-sucrose potency.</p></div>
<div class="how-card"><h4>3 Β· Aroma β 24 odor heads</h4><p>One random forest per descriptor (citrus, floral, woodyβ¦), trained on <b>public-domain odor text</b>. A head ships only if it clears <b>CV-AUROC β₯ 0.70</b> β 24 survive, each shown with its own score. It reads <b>presence, not intensity</b> (free text carries none) β an honest ceiling, stated in the UI.</p></div>
<div class="how-card"><h4>4 Β· Honest by design</h4><p>Every value is tagged <b>measured / predicted / estimate</b>, so nothing reads as more precise than it is. Where a quantitative feature needs data we can't ship free-commercially (odor thresholds, panel intensities), the UI <b>says so</b> β and it lights up with <b>your</b> data.</p></div>
<div class="how-card"><h4>5 Β· Formulation, not just molecules</h4><p>The <b>Formulation Studio</b> reads a whole recipe before you pour β weighting each ingredient by odor impact, aggregating the blend's note-profile, flagging the overpowering component, and closing the gap to your target. That's single-molecule ML turned into a bench tool.</p></div>
<div class="how-card"><h4>6 Β· On-prem & commercial-clean</h4><p>Nothing leaves the box β a read makes <b>no cloud calls</b>. The shipped models train only on <b>public-domain or permissively-licensed</b> data, so the commercial edition stays clean (provenance tracked in the repo).</p></div>

<summary>How it's built & how to read it</summary>
<div class="map-method-body">
<p><b>Method.</b> Each molecule becomes a 2048-bit <b>Morgan fingerprint</b> (radius 2 β
a bit for every local atom environment). Distance between two molecules is
<b>Jaccard = Tanimoto</b> on those bits, the standard chemical-similarity measure. That
high-dimensional space is projected to 2D/3D with <b>UMAP</b>, which preserves each
molecule's <i>local neighborhood</i> β so dots that sit together really are built from
the same substructures. The layout is deterministic (fixed seed).</p>
<p><b>How to read it.</b> The <i>positions</i> come purely from <b>structure</b>; the
<i>colors</i> are a flavor label laid on top. Where a color forms a clean island,
structure alone predicts that flavor (e.g. sugar-like polyols cluster sweet; alkaloid
scaffolds cluster bitter). The interesting molecules are the <b>off-color dots inside
another cluster</b> β a bitter point sitting among sweeteners is a structure that breaks
the trend, exactly the kind of lead worth a closer look.</p>
<p><b>Two flavor dimensions.</b> Flip the color toggle between <b>taste</b> (sweet /
bitter / umami / sour / salty / tasteless) and <b>aroma</b> (= odor β the same thing;
the 24 documented descriptor classes like citrus, floral, sulfurous). Same molecules,
same structural layout β you're overlaying a different sense. The <b>both</b> toggle merges
them into one full-flavor view: each dot takes its <b>taste</b> color where a taste is known,
otherwise its <b>aroma</b> color β so nearly every molecule is colored by its dominant known
flavor property. Comparing taste-only vs aroma-only vs both shows where the two senses align
(a sweet-tasting molecule that also reads floral) versus diverge.</p>
<p><b>Honest caveats β and the fix.</b> The <i>similarity</i> (UMAP) layout has axes with
<b>no units</b>; only local distances mean anything. When you want <b>real, labelled
axes</b>, switch the layout toggle to <b>property axes</b>: the same dots replotted on
<b>molecular weight</b> (x, in daltons) vs <b>logP</b> (y β hydrophobicity, oil-vs-water
partitioning), with gridlines and a logP = 0 waterline. That view <i>is</i> a metric
space β you can read a molecule's size and greasiness straight off the axes, and watch a
taste/aroma color track (or not track) those physical properties. In <b>3D</b>, property
axes add a real third dimension: <b>TPSA</b> (topological polar surface area β polarity /
H-bonding), so it's MW Γ logP Γ TPSA. Two lenses on the same molecules:
<b>similarity</b> for neighbors & outliers, <b>property axes</b> for physical structure.</p>

Bars are model predictions; a <b>measured</b> tag means the molecule is in the
curated data (ground truth, not a guess). The trained taste/tox heads are fit on
<b>organic</b> molecules β carbon-free inputs are flagged out-of-domain. Salty is
lookup-only, sour is a rule. Tox-assay flags are <b>indicative, caution-only</b>
(Tox21 in-vitro models) β never a determination. Quantitative dosing / odor-activity
needs odor-threshold tables (licensed or customer data), so it stays qualitative here.
Substitutions rank by structural similarity (Tanimoto). Aroma isn't in the public
demo β it trains on your data, on-prem. Results are leads for the bench, not verdicts.
